Struct TransformationStack 

pub struct TransformationStack { /* private fields */ }

A stack-allocated buffer for transformations to avoid heap allocations in the hot path.

This structure uses a fixed-size array and is extremely fast for frequent updates.

Implementations

impl TransformationStack

pub fn new() -> Self

Creates a new, empty transformation stack.

pub fn push(&mut self, t: Transformation)

Pushes a new transformation onto the stack. Does nothing if the stack is full.

pub fn pop(&mut self) -> Option<Transformation>

Removes and returns the last transformation from the stack.

pub fn clear(&mut self)

Clears all transformations from the stack.

pub fn len(&self) -> usize

Returns the number of transformations currently in the stack.

pub fn is_empty(&self) -> bool

Returns true if the stack contains no transformations.

pub fn as_slice(&self) -> &[Transformation]

Returns a slice containing all transformations in the stack.

pub fn as_mut_slice(&mut self) -> &mut [Transformation]

Returns a mutable slice containing all transformations in the stack.

pub fn extend_from_slice(&mut self, other: &[Transformation])

Appends a slice of transformations to the stack.

pub fn drain_to(&mut self, start: usize, target: &mut TransformationStack)

Drains transformations from a starting index into another stack.

Trait Implementations

impl Clone for TransformationStack

fn clone(&self) -> TransformationStack

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TransformationStack

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TransformationStack

fn default() -> TransformationStack

Returns the “default value” for a type.

impl Hash for TransformationStack

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TransformationStack

fn eq(&self, other: &TransformationStack) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
